This book teaches and uses only the notes on the viola D string. Using exercises and carefully chosen short pieces, viola students are carefully guided through basic note-reading and playing starting with just one note and adding one note at a time. This book is especially helpful as a note-reading method for younger students or as a supplement for older students who struggle to read notes. The book could be studied after The A-String Book for Viola, studied along with Learning the Viola, Book One, and could be followed by Playing the Viola, Book One.
